Synopsis : This directory, available exclusively in English, includes scientists who disagree on generally accepted positions exclusively in the field of physics (natural philosophy), referenced to on the Internet and in particular those who propose alternative solutions.

The list includes more than 8000 names of scientists, doctors or engineers for more than 50%. Their position is shortly presented together with their proposed alternative theory when applicable. There are more than 1000 theories, all amazingly very different from one another.

In the Soviet era, the term dissident could refer to a political dissident but then as now it mainly has to do with differences about the status of leading theories. Every major scientific theory has its dissidents. And many dissidents have lost jobs or research funding for speaking out. See, for example, Jerry Bergman and Kevin Wirth’s Slaughter of the Dissidents (2011).
